Recently applied for a Saudi PCC in Jeddah.
Process is the same as mentioned in the first post of this thread.
The Jeddah Police Headquarter is located near Khaimah Market, in front of the IDB entrance.

Everybody was generally very nice and courteous over there so far.
Please apply for the PCC soon if you are expecting to get an invite in the next two draws. It takes time for the police to process it. I submitted my application on March 8th and they have called me back on March 19th.
About the MOFA fees- you can pay online and take a print out of the payment confirmation (SADAD) along with the Consulate/Embassy letter. Saving of 20 riyals for two MOFA attestations. Although I was carrying my passport with me, the attestation officer did not ask for either the passport or the Iqama.
For Indians, BEWARE of the VFS India office in Jeddah though. They overcharge severely for filling forms. Please register online MEA India website and when applying for PCC, select Saudi Arabia as the country for which PCC is needed. The generated form will be accepted by the consular officer in the VFS office. They do not accept forms filled out on plain paper anymore. Use the MEA website and save 30-40 riyals.
