Blood Donors in Karachi — Verified Donor List

Karachi is the largest city in Pakistan and its blood demand reflects that — trauma from road accidents, a very large thalassaemia patient population dependent on regular transfusions, and obstetric emergencies across dozens of hospitals. What makes a Karachi blood search hard is rarely a shortage of willing donors. It is distance and traffic: a matched donor in Korangi is no help to a patient in North Nazimabad at 6pm.

If you are searching right now, work through the checklist below in order — it is the fastest route from “we need blood” to a unit actually cross-matched and hanging.

Need blood in Karachi right now? Start here

Write down the exact requirement. Blood group, component (whole blood, packed red cells, platelets or plasma), number of units, and by when. Ask the treating doctor to confirm it — a wrong component wastes hours.
Ask the hospital blood bank what they already hold. A large share of requests are met on site and never need an outside search at all.
Note the hospital name, ward and the attendant’s phone number. Every donor who responds will ask for these three things first.
Widen the search using compatible groups, not just the exact one. An A+ patient can also receive O+, O− and A−. Check the compatibility chart before you start calling.
Reach matched donors nearby, not everyone. A broadcast WhatsApp forward reaches thousands of people who cannot help and few who can. GPS matching alerts only verified donors of the right group who are close enough to actually arrive in time.
Confirm the cross-match at the blood bank. Paper compatibility is never a substitute for a laboratory cross-match.

Blood banks in Karachi

Karachi has some of the strongest non-profit blood banking infrastructure in the country. If the treating hospital cannot supply the unit, these are the names most families are directed to. Confirm current timings and requirements directly with each — do not rely on numbers circulating on WhatsApp.

Husaini Blood Bank — one of the oldest and largest voluntary blood banks in the city, with multiple collection centres.
Indus Hospital Blood Center — a large voluntary, non-remunerated donor programme attached to a free-of-cost hospital network.
Fatimid Foundation — long-established, with a particular focus on thalassaemia and haemophilia patients.
Aga Khan University Hospital blood bank — hospital-based, with its own donor requirements.
Government and teaching hospital blood banks attached to Civil Hospital, JPMC and Abbasi Shaheed.

Most Karachi blood banks work on a replacement basis: a family member or friend donates a unit in the patient’s name and the bank issues the unit the patient needs. Having one or two donors lined up before you arrive shortens the process considerably.

Why a GPS-matched donor network helps in Karachi

Karachi’s size is the problem GPS matching is built for. Instead of forwarding a request across the whole city, GeoBlood shows verified donors of the compatible blood group sorted by how close they actually are to your hospital, and lets you message them inside the app without either side sharing a phone number.

Verified donors. Blood group, donation status and member-since date are shown on every profile.
Matched alerts. Only donors of a compatible group within range are notified, so requests do not get ignored as noise.
Private messaging. Donors and families coordinate inside the app; neither side has to publish a phone number.
Free, and nonprofit. GeoBlood is a registered 501(c)(3) (EIN 99-3116321), run entirely by volunteers. No fees, no paid listings.

Become a donor in Karachi

The reason searches fail is almost never that nobody in Karachi is willing — it is that willing people are not registered anywhere findable. If you are 18 to 60, over 50 kg and in good health, registering takes a couple of minutes and you can set your own availability. Check the full criteria on our blood donation eligibility guide.

Blood donor list in Karachi

There is no single public register of blood donors in Karachi, and the lists that circulate on WhatsApp and Facebook groups go stale within weeks — numbers change, people move city, and donors who gave last month are not eligible again yet. GeoBlood keeps the list live instead: every donor confirms their blood group and last donation date, and only donors who are currently eligible and within range of your hospital appear in a search.

Blood donor contact numbers in Karachi

GeoBlood deliberately does not publish donor phone numbers. Public donor lists get scraped, and donors who end up on them stop answering — which is why most of the lists circulating for Karachi no longer work. Matched donors are contacted through in-app messaging instead: the family and the donor agree a hospital, a ward and a time without either side handing out a personal number. If a donor chooses to share their number in that conversation, that is their decision to make.

Frequently asked questions

How do I find a blood donor in Karachi urgently?

Get the exact blood group, component and number of units from the treating doctor, ask the hospital blood bank what they already hold, then search for matched donors near the hospital. The free GeoBlood app shows verified donors of compatible groups sorted by distance from your location in Karachi and lets you message them in-app.

Which blood banks in Karachi provide free blood?

Several non-profit blood banks in Karachi, including Husaini Blood Bank, Indus Hospital Blood Center and Fatimid Foundation, provide blood at no cost or minimal processing cost, often on a replacement basis where a donor gives a unit in the patient's name. Confirm current policy directly with the blood bank.

Is there a blood donation app for Karachi?

Yes. GeoBlood is a free 501(c)(3) nonprofit app available on iOS and Android that matches verified blood donors and recipients by blood group and GPS location, including across Karachi. There is no charge to donors or recipients.

What is the most common blood group in Karachi?

Pakistan-wide, B is the most common ABO group at about 33.4%, closely followed by O at 33.1%. Roughly 9.4% of the population is Rh negative, which is why negative-group requests in Karachi take the longest to fill.
