Somchai Srisuthiyakorn, an EC member in charge of election administration, said the Thai-Japanese sports complex at Din Daeng is still the venue for registration.
The EC had not asked for more police to extra provide security, believing there would not be a repeat of the violence on Thurday.
Mr Somchai said he would hold a video conference with the election committees in various provinces on preparations for the registration of candidates running in constituencies from Dec 28 to Jan 1.
He said the official cars used by himself and EC secretary-general Puchong Nutrawong were slightly damaged in yesterday's clash.
Mr Puchong said the EC would be responsible for the damage done to the Din Daeng sports complex, which is under the jurisdiction of the Bangkok Metropolitan Administration.
Pol Maj Gen Wichanwat Borirakkul, chief of Metropolitan Police Divison 1, said 10 companies of police had been deployed at the sports complex.
Representatives of five political parties - Mahachon, Pheu Prachachonthai, Pheu Pan Din, Pattana Khunnaphap Cheewit and Palangchon - showed up for registration Friday morning.
