How many phone numbers do you have memorized? These days I only know a few but I used to know dozens.

I know half a dozen. All from the 80s and 90s, and only two which actually exist today.

Other than that I know mine and my wife’s.

Oddly enough I knew a company which had a phone number which was two digits transposed from my home number - 818614. My number until about 1993 was 818641. Didn’t realise the company was still going until a couple of weeks ago when a lorry pulled up outside my window with the name and phone number on.

The other number I remember is my school number for some reason, I can’t think of ever have rung it. It’s still the same number today, 30 years later.

A few family, a few friends, some past work numbers, some of my phone numbers from a decade or two ago when I occasionally changed them, the Apple switchboard because I might have bled in six colors a long time ago, and of course Jenny because if not for her I'd have no clue whose phone number to give to the grocery store checkout system.

More IP addresses than phone numbers for me, but around a dozen of each.
