my apologies, I should have been more clear.

I have an account number that lookes like this: BTX####.(#### being numbers) Join date was August 15, 1988. Not sure if the "TX" means the state, but that was where I lived back then.

Sometimes AA agents would ask me if I read the number wrong... because apparently most members have numbers that start with one alphabet followed by 6 numbers.

just wondering why my acct number looks like that.
