Mexico changed a lot in the past eighteen months — and most of it affects you directly.
Taxes. Residency costs. Your mobile phone line. Labor rules. Real estate paperwork. Data privacy. Public security. Sixteen significant laws, passed or implemented in rapid succession, are reshaping daily life for expats and residents alike.
⚡Some are straightforward wins. Others introduce new obligations, rising costs, and digital deadlines that catch people off guard. None of them are worth ignoring.
Whether you're a Mexican national, expat, retiree, digital nomad, property owner, or business operator, at least some of these changes may affect your daily life.
TWIG reviewed official government sources, legal texts, and expert commentary to create a practical, plain-English guide you can actually use.
⚠️ Most urgent: Deadline June 30, 2026 — 15 days away
01 — Mandatory Mobile Phone Line Registration
Risk level: URGENT — applies to every single person with a Mexican mobile line
This is the most time-sensitive item in this entire guide. Every active mobile line in Mexico — prepaid or postpaid, old or new SIM — must be registered to an official identity before June 30, 2026. Lines not registered by July 1 will be suspended. Only emergency calls (911, 088, 089) will still work. No SMS, no data, no WhatsApp, no 2FA verification codes.
📋 What changed
On December 9, 2025, Mexico's Comisión Reguladora de Telecomunicaciones (CRT) published the mandatory mobile line registration requirement in the Diario Oficial de la Federación. The registration window opened January 9, 2026 and closes June 30, 2026. The CRT has confirmed there will be no extension — it is fixed in law. As of late May 2026, only about 31% of Mexico's 158 million active lines had been registered.

👥 Who must register
Everyone — no exceptions by plan type, line age, or nationality. This includes expats and foreign residents using a Mexican SIM. Prepaid chips bought years ago must be registered. Postpaid contract lines must be registered.
There are no fines for non-registration, but the suspension is immediate and affects your banking apps, social media, digital services, and any 2FA codes sent by SMS.
✅ Stated purpose
Eliminates anonymous SIM cards used in extortion and fraud calls
Links each number to a verified identity to aid criminal investigations
Aligns Mexico with similar registries in other countries
⚠️ Potential concerns
Millions of prepaid users — often lower-income — risk losing service if unaware
Only ~31% registered by late May despite the deadline being weeks away
Scammers are actively impersonating carriers to steal personal data during registration
Privacy advocates question the security of centralized identity-linked phone databases
✔️ What you should do — do this before June 30
Register directly with your carrier — Telcel, AT&T, Movistar. Never use third-party links, respond to unsolicited calls, or click SMS links claiming to be from your carrier.
How to register:
📍 In person: Visit your carrier's customer service center with valid ID + CURP
💻 Online: Log into your carrier's official app or website
📞 By phone: Call your carrier's official customer service line
Documents you'll need:
Official photo ID — your passport works as an expat
Your CURP (certified)
🚨 Scam warning
The CRT has confirmed that carriers are NOT calling users to collect registration data. Any call requesting your personal details, passwords, or bank codes under the guise of line registration is a phishing attempt. Hang up immediately.
You can also check which lines are currently registered to your CURP via the CRT's public portal — useful for detecting any lines registered in your name without your knowledge.
