Wedding invitation etiquette (guest and abbreviations)

We wrote and guest. And as far as the apartment that would be on a line underneath the street address. We also didn’t use abbreviations for words like street and apartment.

I didnt use any abbreviations and spelled most things out, aside from street numbers and zip codes. I think it really just depends on if you are having a more formal wedding or if you will be having a more casual wedding. If youre going for casual, you can abbreviate and use the amphersand and what not. Im just a bit of a perfectionist so i wouldnt have abbreviated street names regardless lol

For the address it should be
123 Safe Street
Apt. B
City, State (spelled out in formal, so Georgia not GA) Zip Code

Formal, you spell every word out with no abbreviations or symbols like &, anywhere except in postal address codes including the state abbreviation. Those have nothing to do with manners, they are to ensure machine readers can process the mail. And are codified in law as correct, therefore something more flowery is not " more correct" or better etiquette. To somehow look more formal, but arrive 5-7 days later, is NOT desired good manners. Also , never put return addresses on the center back. When things come down a mail chute, machines do not know front from back, and anything center front of either side may be read as the address. It may cross the country through a series of vehicles, get to the delivery PO, then someone will see it as wrong, and send it off again, with a magic marker line across one side. Or, a bunch may come back to you never delivered. So, formal, spell out all words including Apartment, and have apartments or suites on a separate line. But do use postal State Zip, not what was traditional, Georgia, but current correct, GA. Even the Miss Manners and Posts type etiquette mavens swapped over some years back. . . For your later things, use the formality of that event, not overall wedding formality. For example, if the rehearsal dinner will be a cookout in the yard, informal style note cards, addressing style, or even phone calls and emails, are perfectly fine. They do not have to be as formal as the coming wedding. Abbreviations and symbols fine then. 123 Elm Street #6 on a single line would be fine, or 123 Elm St. Apt 6. This is an option for other people's casual style weddings, even on invitations.

For formal invitations, hire a calligrapher. Do not have the envelopes typed. Do not use labels, either.
