They've noticed that there are still a lot of mistakes being made with state and country codes. We had Chris check which inputters were making the mistakes, and it turns out the problem is quite widespread. You should be checking your manual for the correct codes. Feel free to leave the manual on your desk open to that page for easy reference. With that in mind, here is a repeat of a post from July 13, 2015.
State and country codes
We've noticed incorrect state and country codes being used recently. It's not uncommon for this to happen. Please don't assume you know the two-digit code, especially all of you who are new. Here are some commonly confused state and country codes.
- Nebraska is NE not NB, which is New Brunswick.
- Arkansas is AR not AK, which is Alaska. We rarely input AK.
- England is EN not EG, which is Egypt.
- Indian Territory is RT not IT, which is Italy.
- Prussia is PU not PR, which is Puerto Rico.
Bonus fun fact: German states have their own codes. So if the person was born in Bavaria, you may type BV, Brandenburg is BR, etc.
If you're not sure what the correct code is, they can all be found in Appendix A of your manual.
