Does anybody know you key-in the alpha part of the new UA MP number? PMUA numbers were all numeric so no confusion.

e.g. do I dial "12" to represent "AD"?

I find that when I do so, it seems to send me to a queue with a long wait (minutes). Instead if I say my number (instead of keying it in), I get an additional prompt asking me to confirm my zipcode. This prompt does not occur when I key in my number. After entering my zipcode, I get a rep in (usually) seconds.

I'd rather not have to say my number aloud.
