In a communication, the Home Ministry said the step was being taken to make sure no one receives remuneration by providing a fake name.
The ministry has also asked the Jammu and Kashmir government to ensure that the process to recruit around 4,200 SPOs is fair, transparent and free from political interference.
The state government has been told to put in place a screening process for recruitment of SPOs and also look into the mechanism to review the antecedents and performance of existing SPOs, the Home Ministry official said.
An SPO initially draws Rs 5,000 per month, Rs 5,300 after completion of one year and Rs 6,000 after completion of three years.

When the recruitment process of the SPOs had started late last year, thousands of youths across Kashmir had turned up, defying militants' threats and the separatists' boycott call
The authorities have received over 25,000 applications from aspiring candidates willing to serve as SPOs from across the 10 districts of the valley.
Separatists had asked the youths to ignore the "enticement aimed at breaking their ranks", alleging that the government was trying to revive "Ikhwan" militia of the 1990s to crush the "freedom struggle"
