In short
The Integrated Service Centers are the State Department’s network gathering services from more than 20 government agencies under one roof, in 21 municipalities: Arecibo, Ciales, Guayama, Guaynabo, Humacao, Lares, Las Marías, Loíza, Mayagüez, Minillas and Río Piedras in San Juan, Moca, Patillas, Ponce, Rincón, San Sebastián, Toa Baja, Trujillo Alto, Vega Alta, Vieques and Yauco. Network agencies include the Demographic Registry, DTOP/CESCO, Treasury, the Department of the Family, the Department of Labor, Medicaid, WIC, the State Elections Commission, the State Insurance Fund, the Retirement Systems Administration, LUMA and more. Appointments are booked online at csicitas.estado.pr.gov. Before travelling, verify which services your specific center offers: not every agency attends at every center.
What is it?
It is the government’s bet that you should not have to pilgrimage from agency to agency: a physical center where several agencies serve the public in one place. For everyday procedures — a birth certificate, a CESCO transaction, a Treasury matter, the Medicaid card, a WIC appointment — the CSI can save trips to San Juan or to each agency’s central office. The network is run by the State Department, has 21 centers across the island, and a single appointment portal.
Who can do it?
There are no eligibility requirements to use a CSI: they are public service offices. What you do need is whatever your specific procedure requires — the documents for the certificate, license or benefit you are handling — because the CSI is the window, not a different procedure with rules of its own.

Step by step
Step 1: Check whether there is a CSI near you
The 21 centers are in Arecibo, Ciales, Guayama, Guaynabo, Humacao, Lares, Las Marías, Loíza, Mayagüez, Minillas (San Juan), Moca, Patillas, Ponce, Rincón, Río Piedras, San Sebastián, Toa Baja, Trujillo Alto, Vega Alta, Vieques and Yauco. The center directory with addresses is at csi.pr.gov.
Step 2: Confirm your procedure is served at that center
The network includes more than 20 agencies — State, Treasury, Family, Labor, Natural Resources, the Elections Commission, the Demographic Registry, DTOP/CESCO, Vocational Rehabilitation, the Economic Development Bank, the State Insurance Fund, Retirement, Medicaid, WIC, LUMA, the Lottery and more — but not every agency attends at every center. Before travelling, check your center’s page at csi.pr.gov or call (787) 722-2121 and confirm the service you need is available there.
Step 3: Book your appointment online
The appointment portal is csicitas.estado.pr.gov. Arriving with an appointment saves you the walk-in line, and the portal lets you pick the center and the service.
Step 4: Arrive with the procedure’s documents, not just the appointment
The CSI is the window; the requirements come from the procedure’s agency. If you are going for a Demographic Registry certificate, a CESCO matter or a Treasury certification, first review that procedure’s PRFácil guide and bring what it asks. The appointment does not replace the documents.
Where to do it
Appointments online: csicitas.estado.pr.gov. Directory of the 21 centers: csi.pr.gov. Phone: (787) 722-2121. Email: csi@estado.pr.gov. The programme is run by the State Department (Calle San José at San Francisco, Old San Juan; PO Box 9023271, San Juan, PR 00902-3271).
How long it takes
What to do if something goes wrong
If the appointment portal does not show the service you seek at your center, don’t assume it doesn’t exist: it may be offered only at some centers or served without appointment — call (787) 722-2121 or write to csi@estado.pr.gov and ask about your procedure and center. If the procedure you need belongs to an agency outside the network, the CSI cannot resolve it: go to that agency’s PRFácil guide for the direct route. And if you live far from the 21 municipalities with a center, remember many of these procedures have their own online route that can save you the whole trip.
Common mistakes
- Assuming every agency attends at every center: the offering varies by center, and confirming beforehand avoids a wasted trip.
- Arriving without an appointment when the portal offers one: csicitas.estado.pr.gov exists precisely for that.
- Going with the appointment but without the procedure’s documents: the CSI is the window, requirements belong to the agency.
- Not knowing the center exists: if your town is on the list of 21, you may have spent years travelling to San Juan for nothing.
- Confusing the CSI with an agency: it belongs to the State Department and coordinates service, but each procedure still belongs to its agency.
Frequently asked questions
Which agencies attend at the CSIs?
The network publishes more than 20: the State Department, Treasury, Family, Labor, Natural Resources, the State Elections Commission, the Demographic Registry, DTOP/CESCO, Vocational Rehabilitation, the Economic Development Bank, the State Insurance Fund, the Retirement Systems Administration, Medicaid, WIC, LUMA, the traditional Lottery, the Public Transportation and Services Board and the municipal Permits Management Office, among others. What each specific center offers is verified on its page or by phone.
Do I need an appointment or can I walk in?
The csicitas.estado.pr.gov portal is the route the network promotes, and arriving with an appointment secures your turn. If your service does not appear in the portal, call (787) 722-2121 to confirm how your center serves it.
Does the CSI charge for serving me?
The network’s page describes no charge for the service itself; what you pay is whatever your procedure costs at its agency (certificate fees, stamps, duties). The exact cost depends on the procedure, not the CSI.
