Pennsylvania Statutes Title 25 Pa.C.S.A. Elections § 1507. Canvass of registered electors

(a) Verification.--The commission may, by individual commissioners or by inspectors of registration, verify the registration in an election district by visiting each building from which an elector is registered and other buildings as the commission deems necessary. The commission shall make a record of the name and address of each person registered who is not found to reside at the address from which the person is registered or who for any other reason appears to be not qualified to vote in the election district from which the person is registered. The commission shall leave at the address of each such person the notice prescribed by section 1506(e) (relating to checkup of registers).

(b) Action.--At the expiration of the time specified in the notice under section 1506(e), the commission shall cancel or suspend the registration of each such person who has not communicated with the commission and proved qualifications as an elector.

(c) Special inspectors.--For the purpose of facilitating a canvass, the commission may, when necessary, appoint special inspectors of registration in number not exceeding double the number of election districts which the commission determines to canvass. They must be qualified electors of the county. They shall be appointed without reference to residence in election districts or to their political affiliations or beliefs. The commission shall instruct each special inspector in discharging duties.
