The government's confirmed death toll of 6,201 has not been updated for a month, as officials investigate whether the recently-discovered corpses are among the 1,785 listed as missing.
UN undersecretary-general for humanitarian affairs Valerie Amos recounted the shock of discovering the dead during a visit Wednesday to the devastated central city of Tacloban.
"As the debris is cleared, they are finding more dead bodies. We experienced that for ourselves," she told reporters.
Amos visited Tacloban to inspect the progress of the UN-aided rehabilitation effort and check on the condition of survivors of one of the strongest typhoons ever to hit land.
The government's National Disaster Risk Reduction and Management Council confirmed bodies are still being found.
"Sometimes they find two or three a day, then there are days where they find none," its spokesman Reynaldo Balido told AFP.
The latest casualty figures were a month old and did not reflect any subsequent corpse retrievals as the authorities work to reconcile the numbers, he added.
