Under the 2023 districting plan adopted by the National Electoral Institute (INE), which is to be used for the 2024, 2027 and 2030 federal elections,^[6] Puebla's congressional seat allocation rose from 15 to 16. The first district is in Puebla's Sierra Norte region in the extreme north of the state and covers 195 electoral precincts (secciones electorales) across 17 of the state's municipalities:^[7][8]

• Chiconcuautla, Honey, Francisco Z. Mena, Huauchinango, Jalpan, Jopala, Juan Galindo, Naupan, Pahuatlán, Pantepec, Tlacuilotepec, Tlaola, Tlapacoya, Tlaxco, Venustiano Carranza, Xicotepec and Zihuateutla.

The head town (cabecera distrital), where results from individual polling stations are gathered together and tallied, is the city of Huauchinango de Degollado. The district reported a population of 397,252 in the 2020 census and, with Indigenous and Afrodescendent inhabitants accounting for over 57% of that total, it is classified by the INE as an indigenous district.^[1][a]

The districting scheme in force from 1978 to 1996 was the result of the 1977 electoral reforms, which increased the number of single-member seats in the Chamber of Deputies from 196 to 300. Under that plan, Puebla's seat allocation rose from 10 to 14.^[9] The district's head town was the state capital, Puebla, and it covered parts of the city and of its surrounding municipality.^[16]
