You look it up in the corresponding July issue of the USPOD Postal Guide. <<<<That teaches you to fish.

Unless on John Becker does it sooner, I will look it up in 3-4 hours.

Edit:

Give me one or two examples, date, city and state and I will show you. Pictures would keep it interesting.

Thanks for the help. I am always learning here! It's GREAT!

Here's one

Always best to work from an illustration. Many thanks for adding one.

In this case, there is a street address and Roakone would clearly be large enough for city delivery, and is a "1st class" office. The 1954 date and 2 cent rate would point to this being a single-piece third class rate (effective Jan 1, 1949), in this case an unsealed Christmas card, which the envelope dimensions also point to. It may be sealed now, but no doubt unsealed when it passed through the mails. Also, it should have been cancelled without a date, but that was often overlooked, likely in the interest of speed during a time of high mail volume.

Local non-carrier items would typically look like a local/general delivery letter and be dated, missing a street address and be sealed like this cover:



As for lists, the Postal Guides varied over the years in the way they indicated carrier offices. As a convenient source for carrier information in this era, the July 1943 Postal Guide appears to be the last with the Classified List of Post Offices with Salaries (pages 895-962), which also indicates those with carrier service. Specifically an excert from the Virginia section, page 947, where,
G=Government owned building
F=City Delivery
V=Village Delivery



LOL, not my most efficient posting!

So, local delivery mail is really how the letter is addressed. No street number, Local carrier?
If I can go a little deeper, what is a local cover at non carrier post office and a local cover at carrier post office?

Any mailpiece addressed to the same town is a "local" item.
Some cities/towns/villages had carrier service and some did not. Those without carrier service meant you had to go get your own mail at the P.O.



You have an example of each type in this thread.

Thanks for the clarification. I understand now!
