If you use a credit card, they ask for your zip code to verify that you are the person using the card.

My zip code is 60609.

Just like the Spiegel Catalog.

Growing up as a child in Austin, I heard the Mr. Gatti’s pizza commercial hundreds if not thousands of times.

Dail 4 5 9 - twenty two twenty two and get a mr Gatti’s pizza delivered. Just 4 5 9 - twenty two twenty two...

Area code 512.

I had no idea at the time how useful it would be to have a single phone number I can give to people who shouldn’t ask. I called it a few years back, and 20+ years later... mr Gatti’s is still there. I hope they appreciate all my “referrals”. Funny thing is, no one in Houston recognizes the number.... cept my kids, of course :) Second generation Gatti referals!

I use it at a gas station and if you give a zip code that doesn't correspond to the address of your card the card is rejected.

They check it with the CC company before authorizing it's use.
