Last updated: September 16, 2026
A Toyota Tacoma VIN is a 17-character Vehicle Identification Number used to identify the truck and retrieve manufacturer-reported vehicle data. Positions 1 through 3 form the WMI (World Manufacturer Identifier), positions 4 through 8 are Toyota’s manufacturer-defined Vehicle Descriptor Section, position 9 is the check digit, position 10 identifies the model year, position 11 identifies the assembly plant, and positions 12 through 17 form the vehicle’s serial sequence. For the most reliable result, decode the complete VIN instead of assigning a fixed meaning to every Toyota-defined character by itself.
Quick Answer
A Tacoma VIN is a 17-character code that breaks down like this:
- Positions 1 to 3 (WMI): Identify the manufacturer and manufacturing region. Current Mexico-built Tacomas commonly use the Toyota WMI patterns 3TM or 3TY.
- Positions 4 to 8 (VDS): Toyota-defined vehicle attributes such as body, restraint, powertrain, drivetrain, or other configuration data. The exact character mapping varies by model year and VIN pattern.
- Position 9: A calculated check digit used to test whether the VIN is mathematically consistent.
- Position 10: Model-year code. Recent Tacoma examples include R = 2024, S = 2025, and T = 2026.
- Position 11: Assembly-plant code.
- Positions 12 to 17: Vehicle serial sequence.
For a vehicle-specific decode, use the Toyota Vehicle Specification tool and cross-check the VIN with the NHTSA VIN Decoder.
Toyota Tacoma VIN Decoder: What Positions 1–17 Mean
A Tacoma VIN is divided into three main sections plus the check digit. Positions 1 through 3 are the World Manufacturer Identifier. Positions 4 through 8 form the Vehicle Descriptor Section, whose exact coding is defined by Toyota for the applicable vehicle and model year. Position 9 is the check digit. Positions 10 through 17 form the vehicle-identification portion that includes the model year, assembly plant, and serial sequence.
| VIN Position | What It Tells You |
|---|---|
| 1–3 | World Manufacturer Identifier (manufacturer and manufacturing region) |
| 4–8 | Toyota-defined Vehicle Descriptor Section |
| 9 | Mathematical check digit |
| 10 | Model-year code |
| 11 | Assembly-plant code |
| 12–17 | Vehicle serial sequence |
The raw characters are useful, but do not assume that a single character inside positions 4 through 8 always represents the same Tacoma feature across every generation. Enter the full VIN into Toyota’s or NHTSA’s decoder when you need vehicle-specific engine, body, restraint, drivetrain, or equipment information.
Where to Find Your Tacoma’s 17-Digit VIN
Check these locations first:
- Driver’s side dashboard: Look through the windshield at the VIN plate near the left side of the instrument panel.
- Driver’s side door opening: Check the certification label on the door jamb or pillar.
- Vehicle documents: Compare the VIN on the title, registration, and insurance documents with the number on the truck.
The dashboard VIN, certification label, and official documents should agree. Do not confuse an engine number stamped on the engine with the vehicle’s full 17-character VIN. If the visible VINs or paperwork do not match, resolve the discrepancy before buying the truck, ordering configuration-sensitive parts, or relying on a vehicle-history report.

Digits 1 to 3: Tacoma VIN WMI (Manufacturer and Manufacturing Region)
Positions 1 through 3 form the World Manufacturer Identifier. For current Mexico-built Tacomas, common WMI patterns include 3TM and 3TY. Toyota technical information associates 3TM Tacoma production with Toyota Motor Manufacturing de Baja California and 3TY production with Toyota Motor Manufacturing de Guanajuato.
Do not treat the third VIN character as a universal stand-alone assembly-plant code. The dedicated assembly-plant character is position 11. The safest approach is to read the complete WMI and then confirm the plant from a full VIN decode.
WMI Code Breakdown
The WMI identifies the manufacturer and manufacturing region. For the Tacoma examples most relevant to current trucks:
- The leading 3 identifies Mexico as the manufacturing country/region.
- The T is part of Toyota’s assigned WMI.
- The complete three-character WMI, such as 3TM or 3TY, should be interpreted as a unit rather than decoding the third character in isolation.
Older Tacomas used other U.S. and Mexico Toyota WMI patterns depending on the model year and production facility. Use the complete VIN with Toyota or NHTSA when identifying an older truck rather than assuming a current-generation WMI applies.
Country of Assembly
Current fourth-generation Tacomas are assembled in Mexico at Toyota facilities in Baja California and Guanajuato. Earlier Tacoma production also included the United States. Toyota’s San Antonio plant produced Tacomas during part of the third generation, but Tacoma assembly there ended in 2021 as production shifted to Mexico.
| Leading Digit | Country | Tacoma Context |
|---|---|---|
| 4/5 | United States | Found on various older U.S.-built Tacoma VINs; decode the full VIN for the exact plant and year |
| 3 | Mexico | Used on current fourth-generation Tacoma VINs, including 3TM and 3TY patterns |
Toyota announced on July 6, 2026 that it will expand its San Antonio manufacturing campus to support future Tacoma assembly. Toyota said Tacoma production will transition from the Baja California plant to the expanded Texas operation over an approximate four-year period. That is a future production transition; Tacoma production remains associated with Toyota’s Mexico operations during the current transition period.
Manufacturer Identification
Read all three WMI characters together when identifying a Tacoma. On current trucks, 3TM and 3TY are established Tacoma WMI patterns. Then use position 11 or a full Toyota/NHTSA decode to verify the specific assembly plant.
This distinction matters because the WMI and plant code perform related but different jobs: positions 1 through 3 identify the manufacturer/manufacturing region, while position 11 is the assembly-plant character for the individual VIN.
Digits 4 to 8: Toyota-Defined Vehicle Descriptor Section
Positions 4 through 8 form the Vehicle Descriptor Section (VDS). These five characters describe manufacturer-defined vehicle attributes required for the applicable vehicle type. On a Tacoma, the decoded result may identify details such as body or cab configuration, restraint system, engine or powertrain, drivetrain, GVWR-related classification, or other configuration information.
The important limitation is that the five positions should not be treated as a permanent one-character-per-feature chart across every Tacoma generation. Toyota’s VDS combinations vary by model year and configuration. For example, Toyota technical bulletins for recent Tacomas show multiple VDS patterns rather than one fixed sequence that can be safely generalized to every Tacoma.
For exact configuration details, enter the complete VIN into the Toyota Vehicle Specification tool. Toyota’s lookup can provide available basic vehicle information, technical specifications, and factory- or port-installed equipment associated with the VIN. You can also cross-check manufacturer-reported VIN data with the NHTSA VIN Decoder.
If you specifically need original equipment and build-sheet information rather than the meaning of the VIN characters themselves, see How to Read a Toyota Tacoma VIN Build Sheet.
Digits 9 and 10: VIN Check Digit and Tacoma Model Year
Position 9 is the check digit, calculated from the other VIN characters using a standardized mathematical process. Position 10 identifies the model year. These positions are standardized more consistently than Toyota’s manufacturer-defined VDS.
What Does the VIN Check Digit Prove?
The ninth character tests whether the VIN is mathematically consistent. A decoder converts VIN characters into assigned numeric values, applies position-specific weights, totals the products, and uses division by 11 to determine the expected check character.
- A failed check can expose a mistyped or mathematically invalid VIN.
- A passing check means the characters satisfy the VIN check-digit formula.
- A passing check does not by itself prove that the physical VIN plate, title, ownership history, mileage, or vehicle identity is genuine.
Use the check digit as one validation layer, then compare the dashboard VIN, certification label, documents, manufacturer data, and history records.
How the Check Digit Is Calculated
The check digit is computed by assigning numeric values to the VIN characters, multiplying those values by position-specific weights, adding the products, and dividing the total by 11. The remainder determines the check character. If the remainder is 10, the check digit is X.
| Step | Purpose |
|---|---|
| Convert characters | Assign the standardized numeric value to each VIN character |
| Apply weights | Multiply each value by its position-specific weight |
| Add and divide by 11 | Calculate the remainder |
| Compare position 9 | Confirm that the entered VIN matches the expected check character |
How Does the 10th VIN Character Identify the Model Year?
The 10th VIN position follows a standardized model-year sequence that repeats every 30 years. Numbers 1 through 9 represent 2001 through 2009 in the current cycle, followed by letters beginning with A for 2010. VINs do not use the letters I, O, or Q, and the model-year sequence also skips U and Z.
Because the model-year code eventually repeats, do not identify the truck from position 10 alone when two cycles are possible. For applicable passenger vehicles, MPVs, and light trucks, an alphabetic position 7 helps identify the 2010–2039 cycle. A full VIN decoder, the truck’s generation, and its documentation provide additional confirmation.
- Enter the complete VIN in a trusted decoder.
- Read position 10 for the model-year code.
- Cross-check the decoded model year against the registration, certification label, Toyota data, and the physical truck.
Common Tacoma Model Year Codes
Use position 10 to identify the recent Tacoma model-year code. Remember that the sequence repeats after 30 years, so the full VIN and vehicle generation still matter.
| 10th Digit | Model Year |
|---|---|
| A | 2010 |
| B | 2011 |
| C | 2012 |
| D | 2013 |
| E | 2014 |
| F | 2015 |
| G | 2016 |
| H | 2017 |
| J | 2018 |
| K | 2019 |
| L | 2020 |
| M | 2021 |
| N | 2022 |
| P | 2023 |
| R | 2024 |
| S | 2025 |
| T | 2026 |
Digits 11 to 17: Plant Code and Vehicle Serial Sequence
Position 11 identifies the assembly plant. Positions 12 through 17 form the vehicle’s production serial sequence. For current fourth-generation Tacoma VINs, Toyota technical information has used M as the Baja California plant code and T as the Guanajuato plant code.
| Field | Purpose |
|---|---|
| Position 11 | Assembly-plant code |
| Positions 12 to 17 | Vehicle serial sequence |
| Full 17-character VIN | Vehicle-specific identifier used for manufacturer, registration, recall, and history lookups |
The serial sequence distinguishes the vehicle within the manufacturer’s VIN system, but do not use the last six digits alone to infer an exact build date, production day, or trim ranking unless an authoritative Toyota source for that exact model year explicitly provides that interpretation.
What a Tacoma VIN Can and Cannot Tell You
| Question | What the VIN Can Do |
|---|---|
| Model year? | Yes. Position 10 encodes the model year. |
| Assembly plant? | Yes. Position 11 identifies the plant when decoded with the manufacturer’s plant-code information. |
| Engine, body, drivetrain, or equipment? | Often available through the complete Toyota/NHTSA decode, but do not assume every attribute maps to one fixed position across all Tacoma years. |
| Exact build date? | Not from the 17 VIN characters alone. Check the certification label and manufacturer records. |
| Open recalls? | The VIN can be entered into Toyota or NHTSA recall databases to check vehicle-specific campaigns. |
| Accident, title, ownership, or odometer history? | Not encoded in the VIN. The VIN is used to query separate vehicle-history databases. |
| Proof the truck is genuine? | No single decode proves authenticity. Compare physical VINs, documents, manufacturer data, title records, and history information. |

Use Your Tacoma VIN for Specs, Parts, Recalls, History, and Insurance
Your Tacoma’s VIN is the key that connects the truck to several different databases. Those databases serve different purposes, so do not treat a VIN decoder, recall search, and vehicle-history report as the same thing.
- Specifications and equipment: Enter the VIN in Toyota’s Vehicle Specification tool to view available manufacturer-reported vehicle information and equipment.
- Federal VIN decode: Cross-check the full VIN with the NHTSA VIN Decoder.
- Recalls and campaigns: Check both the Toyota recall lookup and the NHTSA Recall Lookup Tool.
- Parts: Use the complete VIN when a Toyota dealer or parts catalog needs to identify configuration-sensitive components. Do not rely on a hand-decoded VDS alone.
- Vehicle history: Use a separate reputable vehicle-history source for available title, accident, odometer, theft, lien, or ownership-related records. Those events are not encoded in the VIN characters themselves.
Insurance companies also use VIN-linked vehicle information when identifying the exact vehicle for quotes and policies. Confirm that the VIN on the insurance documents matches the physical truck.
How to Decode and Verify a Tacoma VIN Step by Step
For the most reliable result, use more than one source instead of trying to hand-decode every Toyota-defined character.
| Step | What to Verify |
|---|---|
| 1. Find the VIN | Read all 17 characters from the dashboard and compare them with the certification label and documents |
| 2. Toyota specification lookup | Check available year, technical specifications, color, and factory/port equipment tied to the VIN |
| 3. NHTSA decode | Cross-check manufacturer-reported VIN attributes and plant information |
| 4. Model year and plant | Confirm positions 10 and 11 agree with the truck’s documentation and generation |
| 5. Recall checks | Run the VIN through Toyota and NHTSA recall databases |
| 6. History check | Use a separate history source when you need title, accident, theft, lien, or odometer information |
If the dashboard VIN, certification label, registration, title, or decoder results conflict, stop and resolve the discrepancy before relying on seller claims, ordering expensive configuration-specific parts, or completing a purchase.

Frequently Asked Questions
What Does Each Part of a Toyota Tacoma VIN Mean?
Positions 1 through 3 are the World Manufacturer Identifier. Positions 4 through 8 are the Toyota-defined Vehicle Descriptor Section. Position 9 is the mathematical check digit, position 10 is the model year, position 11 is the assembly plant, and positions 12 through 17 form the vehicle serial sequence. Decode the complete VIN because Toyota’s positions 4 through 8 can vary by model year and configuration.
How Do I Decode a Toyota Tacoma VIN Number?
Find the 17-character VIN on the dashboard or driver-side certification label. Enter it into Toyota’s Vehicle Specification tool to review available manufacturer vehicle information, then cross-check it with the NHTSA VIN Decoder. Use Toyota and NHTSA’s separate recall tools for vehicle-specific recall information.
Can a Tacoma VIN Tell Me the Exact Trim and Options?
A full Toyota VIN lookup can provide vehicle-specific specifications and available factory- or port-installed equipment, but you should not assume that every trim or option can be identified by manually assigning one fixed meaning to each character in positions 4 through 8. Use Toyota’s complete VIN lookup for the exact truck.
Does a Tacoma VIN Show the Exact Build Date?
No. Position 10 gives the model year and position 11 identifies the assembly plant, but the 17 VIN characters do not by themselves provide the exact day the truck was assembled. Check the certification label and Toyota records when you need manufacture-date information.
Where Are Toyota Tacomas Built?
Current fourth-generation Tacomas are assembled in Mexico at Toyota facilities in Baja California and Guanajuato. Toyota announced in July 2026 that its San Antonio, Texas plant will be expanded for future Tacoma assembly and that Tacoma production will transition from Baja to the expanded Texas operation over an approximate four-year period.
Does a Valid VIN Check Digit Prove a Tacoma Is Genuine?
No. A valid check digit shows that the VIN satisfies the mathematical VIN formula. It can catch many incorrect entries, but it does not prove that the physical VIN plate, title, mileage, ownership record, or vehicle history is authentic. Compare the truck’s VIN locations, documents, manufacturer data, recall records, and history information.
Can a Free VIN Decoder Show Tacoma Accident and Ownership History?
A VIN decoder can identify manufacturer-reported vehicle information, and recall databases can show applicable safety recalls. Accident, title, odometer, theft, lien, or ownership records come from separate vehicle-history databases and are not encoded directly in the 17 VIN characters.
Conclusion
A Toyota Tacoma VIN gives you a reliable framework for identifying the truck, but the safest method is to decode the complete 17-character VIN rather than guessing individual Toyota-defined VDS characters. Use positions 1 through 3 for the WMI, position 9 for the mathematical check, position 10 for model year, position 11 for assembly plant, and positions 12 through 17 for the serial sequence. Then cross-check the full VIN with Toyota and NHTSA.
If the dashboard VIN, certification label, documents, and decoder results agree, you have cleared an important identity check. That still does not prove the truck’s accident, title, mileage, or ownership history, so run the appropriate recall and vehicle-history checks before making a purchase or relying on seller claims.
