A National K–12 Communication Framework for Mexico
School Contact México proposes standardized, verified email domains for schools, students, teachers, families, and universities across all 32 states of Mexico — a secure, Machine Intelligence–ready identity infrastructure built from the ground up for the Mexican education system.
Each domain maps to a specific role in the education system. The area code prefix before the number identifies that role instantly — no ambiguity, no impersonation possible, every address verified against a national registry.
For principals, administrative staff, IT coordinators, counselors, and all school employees who are not classroom teachers. Area code 222 identifies individual school staff; 333 identifies the school or district as an institution; 999 identifies the SEP and federal or state educational authorities.
Exclusively for teachers with an active classroom appointment. Area code 111 is reserved for teachers only. When a parent sees a message from an 111 address, they know it came from a verified, currently employed teacher — not an unverified account.
111 · Active teacherA permanent numeric identifier assigned at first enrollment. The number never changes. As the student advances from primary to secondary and preparatory, only the domain updates. The area code (444, 555, or 777) is simply the pool of numbers the student was assigned from — it does not indicate grade level.
A dedicated domain for parents and guardians within the school system. Schools and teachers can immediately identify that a message comes from a verified family member — not an external, unverified contact. Area code 888 identifies families in the national framework.
888 · FamiliesFor students and staff at universities, technical institutes, and higher education centers across Mexico and Latin America. The Portuguese spelling (universidade) is intentional — this domain is designed with a pan-American scope, built to serve both Mexico and Brazil under a single identity infrastructure. Area code 600 identifies the university community within the national system.
600 · Higher EducationMexico has over 25 million students in basic education and more than 800,000 active teachers. Without a standardized identity system, every school manages communication differently — creating security gaps, inefficiency, and vulnerability to impersonation at scale.
At first enrollment, every child receives a unique, permanent numeric identifier. Parents, teachers, and digital systems know exactly who they are communicating with — without ambiguity, across all 32 states.
The system is designed to comply with Mexico's Federal Law on Protection of Personal Data (LFPDPPP). Third-party platforms never access a student's real name or personal details — only an alias token. Compliance is architectural, not dependent on vendor policies.
The numeric format is optimized for areas with limited connectivity, basic devices, and voice-first interfaces. A 10-digit identifier works equally well at a Mexico City school as at a telesecundaria in Oaxaca.
When a family moves from Monterrey to Guadalajara, the new school queries the national registry and retrieves the student's verified record instantly — no paperwork, no re-enrollment, no lost history.
familia.email gives parents and guardians a verified identity within the school system. Teachers and administrators can immediately distinguish a message from a verified family member from an unverified external sender.
The school devices of tomorrow — tablets, voice assistants, smartwatches — need a machine-readable identity system. The School Contact numeric format is the infrastructure those tools will be built on in Mexico.
This is what the School Contact framework makes possible. It is not a new technology platform that every school must install — it is an identity layer that works on top of existing infrastructure, standardizing the way every actor in the Mexican education system communicates and is recognized.
Mexico has an opportunity to build from the beginning a system that countries with older infrastructure cannot replicate without enormous cost. The window to design it well is open now.
The School Contact framework doesn't end at preparatoria. universidade.email extends the verified identity system to universities, technical institutes, and other higher education institutions across Mexico and Latin America.
The Portuguese spelling (universidade) is deliberate: this domain is designed with a pan-American vision, built to serve both the Mexican and Brazilian education systems — and the rest of the continent — under a single identity infrastructure.
Area code 600 identifies the university community within the national registry.

The School Contact framework was developed in the United States and is now being proposed for Mexico with domain names and role structures tailored to the Mexican education system. The underlying architecture — area codes, permanent identifiers, alias tokens — is identical.
✦ Roles unique to the Mexican framework
The School Contact Initiative is looking for partners in Mexico — pilot schools, educational authorities, and civil society organizations — to help develop the national communication framework.
