Link your red Blak line
By government rule, everyone with a mobile line in Mexico has to link their number to their personal details. It applies to every carrier, not just red Blak.
What does linking your line mean?
It means officially confirming the number is yours by linking it to your personal details. Every carrier in Mexico requires it.
Why do I have to do it?
It's a government requirement for every carrier (Telcel, AT&T, Movistar, Bait and red Blak), not just us.
How do I do it?
You do it yourself in the red Blak app in a few minutes, step by step. No waiting in line, no office visits.
What happens if I don't link my line?
If you don't link your line by the official deadline, your service may be suspended until you do. We'll give you plenty of notice in the app and on our channels.
The deadline and exact steps are set by the current official rules. Check the latest in the app or ask our team.
