How did various area codes in the country vote for president?

Not that I have the actual data on this, I'm 100% sure this list of ones from Southern California all went for Biden. I'm iffy on the rest of the southern Cali ones. This has to be one of the more interesting questions I've seen here

For Washington - no exact numbers, just eyeballing it.

206: Safe Biden, probably around a 50 point win for Biden, and trending further D.
253: Safe Biden, but by a much smaller margin, maybe 15 or so. No strong trend one way or the other.
360/564: Safe Biden, by around 10-15 points, trending D in the northern half and R in the southern half. The southern half is trending faster, but has a smaller population, so probably a modest D trend overall.
425: Safe Biden, hard to say by how much, but I'd guess maybe 15-20 points. Extremely quickly D trending.
509: Safe Trump, probably by around 10-15 points. No strong overall trend, but strong trends in both directions in sub-regions.

615/629 and 931 were for Trump I can tell u that

[Drew]

In WI, 414 is obviously D, 608 is sort of a mashup of the 2nd and 3rd CD’s, so probably D.  262, 920/274, and 715/534 were R, as they are basically the 1st and 5th CDs, 6th and 8th CDs, and the 7th CD respectively.

Based off my calculations, here is how NY's area codes voted

716 (WNY): Biden + 6
585 (Rochester area): Biden + 8
315 (CNY/Finger Lakes/Western North Country): Trump + 4
607 (Southern Tier): Trump + 3
518 (Capital Region/Eastern North Country): Biden + 8
845 (Catskills/NYC suburbs/exurbs): Biden + 5
914 (Westchester): Biden + 36
631 (Suffolk): Trump + <0.1
516 (Nassau): Biden + 10
212/646/917 (Manhattan/SW Bronx): Biden + 74
347/718 (Rest of the Outer Boroughs): Biden + 47

[Roll Roons]

Some in Illinois:
312/773 (Chicago): Obviously went overwhelmingly for Biden
630 (Western burbs): Biden
847/224 (Northern burbs): Biden
217 (Central IL): Went for Trump. Champaign is the only blue county in this area code and it's not nearly enough to outweigh the rest of it.
618 (Far Southern IL): Heavily Trump

This is what the 2020 Presidential election looked like at the area code level:



124 Trump
113 Biden

(not accounting for some districts with two area codes)

[Hope For A New Era]

Missouri:

314 (inner St. Louis) is certainly D, 636 (outer St. Louis), 660 (north), 573 (east/central), and 417 (southwest) are certainly R. 816 (my area code, Kansas City region) is a swing area code. It voted Biden in 2020 (as the map posted above me shows), but voted Trump +3 in 2016 (estimated, as I wasn't able to match the boundaries exactly with DRA).

Which area code had the closest margin?

[RI]

(huge map)

Which area code had the closest margin?

631 in NY, which corresponds to Suffolk County, which Trump won by 0.03%.

[Schiff for Senate]

308 and 531 in NE most likely went red.
915 in TX most likely went blue.
The whole state ones (ID, MT, ND, SD and WY, to name a few) are self explanatory.
I'm too lazy to do more.

[bayareabay]

I know the 415 and 510 (SF and East Bay) must have voted about 85% for Biden.   

[kwabbit]

All of NJ's area codes voted for Biden. 856 (SW Jersey) was Biden +16, as was 609 (Mercer, Burlington, Atlantic, and Southern Ocean). 732 was very close, but from my rough calculations Biden won it by around 1 point. 908 was Biden +17 and bears a very strong resemblance to the new NJ-07 but with more of the Dem cities in Union County like Plainfield and Elizabeth. 973 was Biden +24 and includes Sussex, Passaic, Morris, and Essex. 201 includes Hudson and Bergen Counties and was Biden +26. I was a little surprised Biden won all of them, I figured 732 would include more of the shore so Trump could've carried it.
