406 came first, in 1947

Montana, by the numbers.
Montana has used a single area code, 406, since the North American Numbering Plan began on January 1, 1947.
Montana was large in land area but sparsely populated, so one code covered the whole state without strain.
Low population density kept demand manageable through the wireless boom of the 1990s and 2000s, and number pooling stretched the supply further.
406 remains the only area code most Montanans have known — a point of local pride on license plates and business names statewide.
Montana is one of only a few U.S. states where a single area code, 406, has covered every corner of the state without a single split or overlay since the very first day of the North American Numbering Plan in 1947.
