DETROIT (Michigan News Source) – Across the state of Michigan, communities have been celebrating their area codes, some quietly and others not so quietly. Today, March 13th, is 313 Day in Detroit and they are embracing the merrymaking. Today’s “holiday” celebrates the culture and history of Detroit and Detroit-ers in the 313 area code. According to 101 WRIF, 313 is “one of the original 86 area codes created by AT&T and the Bell System back in 1947. It includes Wayne county, the City of Detroit and other communities such as Hamtramck, Lincoln Park, Redford, Taylor, Dearborn, Dearborn Heights and Inkster.

Detroit is celebrating 313 Day with parties and deals all over the city. Chili’s Grill & Bar has Presidente Margaritas for $3.13 all day long. The Detroit Symphony is offering tickets for $3.13 for some of their concerts. The Detroit Pistons have a basketball game tonight and have lots of festivities planned and there are concerts and other 313 events planned all over the city.

However, according to the Detroit Free Press, there aren’t going to be any more folks added to the 313 area code soon. They say that the state is running out of 313 numbers and want to add a new 679 code to use in Detroit and some of the surrounding suburbs.

The Michigan Public Service Commission said recently in a news release, “The 313 area code is projected to be exhausted during the third quarter of 2025, which means most phone numbers within the area code are in use, with few to no new numbers available to assign, aside from those returned to the numbering inventory and reassigned through standard industry practice.”

The press release goes on to say, “That will require applying a new area code that will cover the same geographic territory of the 313 area code, without splitting the current area code boundaries or requiring a change of numbers for existing phone users by moving existing 313 phones to a new area code. Rather, current 313 numbers will remain in place while new phone customers in the same territory may be assigned numbers with the 679 area code.”

A public hearing on the matter will be held on March 9th. Those who will be assigned the new 679 area code will not have a day to celebrate as there isn’t a June 79th.

The same problem applies to Northern Lower Michigan, who have an area code of 231. They can’t celebrate on February 31st because there is no such thing and the same is true for the 989, 248, 947, 586 and 734 folks on the East side of the state as well as the 269 folks in the lower southwest corner of Michigan.

A few other parts of the state are lucky enough to have good area codes they can celebrate on – and some are already involved in partying on these days. Lansing, area code 517, celebrates on May 17th with “A Party for the People,” West Michigan has 616 day on June 16th and the Upper Peninsula embraces 906 Day on September 6th.
