I have glass photo negatives of an ad for my dad's diner from way back. The phone number was 527. So strange to think of nowadays!

Do you by any chance remember when zip codes became a thing? With Mr. ZIP on everything to remind us to use that new-fangled zip code on every piece of mail? lol

One guy in town has an old wrecker truck with 3 digit phone on the doors. Its a classic.

...remember when zip codes became a thing?

"The Zoning Improvement Plan (ZIP) Codes were invented by Robert Aurand Moon in the 1950’s although they didn’t come into use by the Post Office until 1963."

... "1974: The first grocery product to be scanned using a Universal Product Code (UPC) is a pack of Wrigley's chewing gum. This took place at a Marsh Supermarket in Troy, Ohio".

... Denso Wave made the QR Code public in 1994. Denso Wave and their lead developer, Masahiro Hara, invented the square 2D Code (two coding directions) to hold more information than bar codes. Quick Response (QR) scanners can read information many times faster than linear barcodes.
