[23] Bellmawr is home to the main post office for the area, one of the largest in the state of New Jersey, handling an average of 4.5 million pieces of mail daily.[24] Bellmawr was authorized to incorporate as a borough on March 23, 1926, from portions of the now-defunct Centre Township, and was made independent based on the results of a referendum held on April 21, 1926.The boroughs of Mount Ephraim, Runnemede and Lawnside were also created in the same two-day period.[31][32][33] The 2010 United States census counted 11,583 people, 4,670 households, and 3,068 families in the borough.[39] As of the 2000 United States census[17] there were 11,262 people, 4,446 households, and 3,134 families residing in the borough.[7] The borough form of government used by Bellmawr is a "weak mayor / strong council" government in which council members act as the legislative body with the mayor presiding at meetings and voting only in the event of a tie.The mayor can veto ordinances subject to an override by a two-thirds majority vote of the council.[43] The members of the Bellmawr Borough Council are Raymond Bider (D, 2025), James P. "Jamie" Casey (D, 2025), James F. D'Angelo (D, 2026), Bill Evans (D, 2024; elected to fill an unexpired term), Johann Fina (D, 2026) and Craig R. Wilhelm (D, 2024).[51] In November 2012, the council selected Joshua Tregear, from among a list of three candidates recommended by the Camden County Democratic Committee, to fill the vacant seat of Regina Piontkowski, who had resigned two months earlier after serving nearly 20 years in office.[54][55][56] For the 119th United States Congress, New Jersey's 1st congressional district is represented by Donald Norcross (D, Camden).[68][61][69][70][71] Camden County's constitutional officers are: Clerk Pamela Rosen Lampitt (D, Cherry Hill, 2029)[72][73] Sheriff Chuck Billingham (D, Gloucester City, 2027)[74][75] and Surrogate Michelle Gentek-Mayer (D, Gloucester Township, 2025).[79] Among the borough's 2010 Census population, 63.6% (vs. 57.1% in Camden County) were registered to vote, including 79.9% of those ages 18 and over (vs. 73.7% countywide).With an enrollment of about 150 students, the Roman Catholic Diocese of Camden announced in June 2009 that the newly combined school would be closed.[112][113] NJ Transit bus service is available in the borough on the 400 route between Sicklerville and Philadelphia.
