When sending packages, greeting cards or business documents to someone, or even looking up an address online or filling in documents for business or personal purposes, you will realize it is essential that you know and use the state postal abbreviation.

The United States is made up of 50 states, all with their own unique two-letter postal abbreviations, it can be tough remembering the two letters required when filling in an address, especially when some states have very similar lettering. Here’s what you need to know about the Maryland state abbreviation.

MD State Abbreviation

There is some confusion when it comes to the Maryland state abbreviation, some people assume that it is the first two letters of the name like the majority of other states, which would make it MA. However, this is not the case, the Maryland state abbreviation is actually the first and last letter of the name, “MD”. Other states with similar spelling, letters, and abbreviations are the Maine State abbreviation and the Massachusetts state abbreviation. The three of these states are often confused with one another.

MD State Abbreviation

Now that you know the two-letter MD state abbreviation, it makes sense to know what the regular state name abbreviation is for Maryland. The regular abbreviations to states’ names came out in 1963, but many were three to four letters in length and it was decided they would be too long to include on envelopes and packages as addressing equipment couldn’t accommodate these longer state abbreviations in addition to zip codes.

The MD state abbreviation is easy to memorize as it is the exact same as the postal abbreviation, the only difference is the name abbreviation is in lower-case with a period at the end, “Md.”. The Old Line State has become an increasingly popular place for business owners and entrepreneurs to move to as there are many local, regional, and national resources available whether you are looking to tackle a government procurement contract for the first time, or wanting certification as a minority, veteran, or women-owned business. If you are interested in checking out the Maryland minimum wage, keeping updated on future increases, and the minimum wage history, check out our page dedicated to this.
