The sites ask for the 4 digit zip code extension, not “area code”.
I guess one could fake it, but, possibly that can be screened out.
BTW, Pelosi’s site says snail mail gets an additional 2 week delay due to “security”. So, that’s not much good.
OTOH, here’s her SF Office info.:
San Francisco District Office

San Francisco, CA 94103.
phone: (415) 556-4862

A few reps may also show a fax # somewhere on their site, but none of the major players seem to, that I’ve seen so far.
“The sites ask for the 4 digit zip code extension, not “area code”.”
Go to website of Senator on Representative.
Look under contacts / offices and find their local office.
Pick THAT zip code and 4 digit extension.
If it doesn’t show th 4 digit extension,
go to https://www.usps.com/nationalpremieraccounts/findzipcodes.htm
Admittedly a PITA but after the first one, it only takes a minute...
