Many people over 75 don't own smart phones or computers or have easy access to someone or someplace that does. Also much of the info about individuals online is incorrect. We really still do need phonebooks for now. Give it another 10 or 15 years and that might change. We need reputable correct online info for peoples names and addresses.
I remember when the Villages gave you a directory of all people in your Village, names, addresses and phone numbers organized by street address. That really was helpful.

The median age for people living in The Villages is 71. Of the posters now viewing your post and who have posted today and are frequent posters, I would say at least a third, maybe more are over 71, and that means that we are using computers. The directory of people in "your village" was likely compiled by a person who lives in your village. That is where we have received our neighborhood lists for the past 15 years.

Only a few of my peers are not computer literate and I am 81.

In Atlanta, there’s a number in the cover of the phone book that you can call to opt out of receiving. We haven’t gotten one in years.
That could be a solution but time consuming for delivery person.

When we bought a home in Milledgeville, Georgia ATT informed us they don’t distribute phone books and that was the first place we lived that did that. Really missed the phone book for local contractors.
