No. However, Smart911 requires you to log into your Safety Profile at least once every 6 months to review your information. You don't actually have to update your info unless something has changed - just a quick login is all that's really required.
These logins are required so that 9-1-1 call takers can be sure that the information they are viewing during your call is accurate.
If your Profile does expire, no problem - simply log back in to reactivate it.
