Not really.

Typically the first thing interns will do is at minimum gather your zip, if not address. Congressional offices receive a fair amount of out-of-district phone calls and non-constituent phone calls will get you a "Thanks for your concerns, have a nice day!"

And, tbh, I sort of disagree with GP's comment about calling every day. Offices might have a high turnover rate, they might not. The offices most definitely do keep track of who calls and they know who the repeat callers are. A lot of time the repeat callers tend to have mental issues (unsure how else to phrase that)—congressional offices get lots of weird phone calls.

I mean yeah, call about issues. It's the best way, other than a face-to-face conversation. (Assuming, too, that the legislator has their CM or an aide with them to take your contact info.) But calling every day will put you on the "ugh, not this guy" list.
