Why Mail Can Take Longer
One truck a day
850 Texas ZIP codes are on USPS's one-truck-a-day schedule (RTO). Mail dropped there after the truck has left waits until the next morning. Check your ZIP code
The slower ZIP list
USPS lists 957 Texas ZIP codes whose First-Class Mail takes a day longer than the rest of their area. The calculator above adds that day.
Longer standards since 2021
In October 2021 USPS lengthened First-Class Mail standards from 1 to 3 days to 1 to 5 days, so it could move more mail on its ground network.

Questions People Ask
Does Saturday count as a mail day?
Yes. USPS delivers Monday to Saturday, so Saturday counts. Sundays and federal holidays are not delivery days. The examples under "Does the Day You Mail Matter?" show the effect on this route.
How many stamps do I need to mail a letter from Texas to California?
One Forever stamp for a standard letter up to 1 oz ($0.82), plus $0.29 for each extra ounce. A letter costs the same to any US address, near or far.
Is Priority Mail guaranteed?
No. Between these two states USPS's standard for Priority Mail is 2 to 3 days, but it is a standard, not a promise. Priority Mail Express is the only USPS domestic service with a money-back guarantee.
Is Certified Mail slower?
No, and not faster either. Certified Mail is an extra service on a First-Class letter: it adds a delivery record, and the letter keeps the First-Class standard (3 to 5 days on this route).
Is mail from California to Texas faster?
A little. The average First-Class standard is 4.2 days from California to Texas, against 4.4 days this way. USPS sets each direction separately.
