Cartilla Militar photos must be 35×45mm — the same size and standard as a Mexican passport photo. No glasses. White background. The Cartilla Militar is issued by SEDENA (Secretaría de la Defensa Nacional) to all Mexican male citizens at age 18, and it's valid for life.
It's not an optional document. Every Mexican male citizen is legally required to complete military registration (Servicio Militar Nacional) and receive the Cartilla Militar. Failing to register carries fines and can block access to other government services.

Same Spec as the Mexican Passport
The Cartilla Militar uses the same 35×45mm format as the Mexican passport and the licencia de conducir. One photo session produces prints that work for all three. If you're a young Mexican citizen turning 18 and applying for your Cartilla Militar, getting passport photos at the same time is practical — the spec is identical.
Who Needs a Cartilla Militar in Mexico? (All Male Citizens)
All Mexican male citizens are required to register for Servicio Militar Nacional (National Military Service) in the year they turn 18. This applies regardless of:
- Whether they actually serve in active military duty (most do not — the "service" is typically a lottery with most men assigned to a social service program rather than active military duty)
- Whether they live in Mexico or abroad (Mexicans living abroad must register at the nearest Mexican consulate)
Women are not required to register, though they may volunteer.
The Cartilla Militar comes in two main formats:
- Cartilla Militar Liberada (Clase 1-A): Issued after completing the service obligation — the most commonly held form.
- Cartilla Militar (in process): Issued while service is being completed.
How to Apply for a Cartilla Militar Through SEDENA
Registration and issuance are administered through SEDENA's regional Jefaturas de Servicio Militar Nacional, typically located at the local military base (zona militar) for your area.
Steps:
- Locate your nearest Jefatura de Servicio Militar Nacional (search on SEDENA's official portal, gob.mx/sedena)
- Complete registration in the year you turn 18 (there's a grace period, but late registration incurs fines)
- Submit required documents: birth certificate (acta de nacimiento), CURP, official photo ID, and 35×45mm photos
- Attend the lottery ceremony (sorteo) to determine your service classification
- Complete any required service obligation (social service, classes, or in rare cases active duty)
- Receive your Cartilla Militar Liberada
| Item | Detail |
|---|---|
| Fee | Free |
| Processing time | 6–12 months (full process including service completion) |

The "6-12 months" reflects the full registration-to-card timeline including completing service. The card itself is typically issued within weeks after service completion is recorded.
Uses of the Cartilla Militar as a Secondary ID in Mexico
The Cartilla Militar is a widely accepted secondary ID in Mexico. It's used:
- As a secondary identity document when applying for other government services
- For proof of age (it shows date of birth)
- For certain employment applications, particularly government positions and security-sector jobs
- For IMSS (health insurance) and INFONAVIT (housing fund) enrolment when other documents are unavailable
- At banks for identity verification alongside a primary ID
It's not a primary travel document — you need a passport for international travel and your INE for domestic purposes. But for a young Mexican man who has just turned 18 and may not yet have an INE card, the Cartilla Militar often serves as the first official government ID.
Photo Tips for Mexican Cartilla Militar Applications
The Cartilla Militar photo follows the same rules as the Mexican passport photo.
No glasses. This is a hard rule. Show up without glasses, even if you normally wear them.
Neutral expression. Eyes forward, mouth closed, relaxed face. Not a forced frown — just a natural resting expression.
White background. Pure white, not off-white or light grey. Professional studio photos are the most reliable way to get this right.
Even lighting. No shadows on the face or visible behind the head. A studio setup handles this automatically.
Bring more prints than you think you need. SEDENA typically requests 2-4 photos at various stages of the registration process — for the initial application, the service file, and the card itself. A standard photo studio session prints 4-6 photos per sitting. Have a set ready.
Expression and Appearance Rules for Cartilla Militar Photos
The Cartilla Militar applies the same biometric standard as the Mexican passport:
- Mouth closed — no teeth visible, lips together gently
- Neutral expression — no smiling, no frowning
- Eyes open — both eyes fully visible, looking directly at the camera
- No glasses — all types banned, including clear prescription lenses
- Hair away from face — forehead visible; for the military registration, hair must be short and neat per SEDENA grooming standards
- Head coverings — not allowed for the Cartilla Militar photo (no hats, caps, or headbands)
- Clean-shaven or neatly groomed — SEDENA may require a clean-shaven appearance during the service period
Common Cartilla Militar Photo Rejection Reasons
Background not white. Off-white, cream, and light grey backgrounds are all rejected. Use a professional studio or photo booth with a controlled white backdrop.
Glasses visible. Even partially visible frames will fail. Remove all eyewear before the photo.
Wrong expression. Smiling or frowning. The biometric standard requires a neutral, natural expression.
Wrong size. Must be 35×45mm. US-format 2×2 inch (51×51mm) photos are too large. Confirm "tamaño pasaporte mexicano" when ordering.
Not enough prints. SEDENA may request 2–4 photos at different stages. Bring at least 4 to avoid return visits.
Mexican Document Photo Sizes Compared
| Document | Size | Background | Glasses | User-submitted photo? |
|---|---|---|---|---|
| Cartilla Militar | 35×45mm | White | Not allowed | Yes — bring prints |
| Mexican Passport | 35×45mm | White | Not allowed | Yes — bring prints |
| Licencia de Conducir | 35×45mm | White | Not allowed | Yes — bring prints |
| INE Voter ID | Captured on-site | — | — | No — photo taken at INE module |
The Cartilla Militar, passport, and licencia de conducir all share the same 35×45mm white-background specification. One photo session covers all three. The INE voter ID photo is captured on-site at INE módulos — you don't bring your own photo for that one.
Registering Late for Mexican Military Service
If you missed the registration window at 18, late registration is possible but comes with fines and administrative complications. Contact your nearest Jefatura de Servicio Militar Nacional or Mexican consulate (if abroad) to begin the process. A compliant photo is still required regardless of when you register.
Late registration becomes more urgent if you need the Cartilla Militar for government employment applications, certain professional licences, or other administrative processes that reference it. In practice, many men register late and the system accommodates this — but it's simpler and cheaper to register at 18.
