- Mailing addresses stretch past city limits here. 2,917 competitive residential meters use Krum as their postal city, while the city itself has 2,014 Census households, a ratio of 1.45. Because Krum has grown 24 percent since the 2020 base, the ACS 2020-2024 household figure likely runs behind today's count.
