lol on a much lighter note, for many years I used to use 111-111-1111 as a general phone number for CVS card discounts. It stopped working several years ago though.

As a Canadian I was lost and confused when visiting the States (in the before time) and a gas pump asked for my zip code. So I put in the one and only zip code I know. I bet you can guess.

This reminds me: I've noticed that Starbucks now requires a few pieces of information to use their WiFi network. One is email and they are doing some sort of validation which will reject emails like whoopsileanedonxxxxxxxx@aol.com but will accept other, legit AOL emails. How are they deciding what is/not a valid email? Are they using a compiled list of emails that have been seen in the wild? What if it's a brand new address, though? Presumably AOL isn't exposing a service for them to use in realtime. I haven't tested this extensively or with other providers.

It's obvious that they care (to some extent) that they're getting valid emails, so why not use a basic regex on the FE and an OTP which gets sent to the provided address?

XXX-867-5309 still works everywhere I try it, where "XXX" is the local area code.

I used 888-888-8888 at Target yesterday. Shhh.

Lookup the stores phone number of maps. That usually works.
