The final stumbling block was 20 disputed centrifuges Iran had that the International Atomic Energy Agency was concerned could be used to enrich uranium to weapons-grade. But Sunday, Tehran backed down from its demand that some centrifuges not be included in the freeze, saying they would not be used.
However, the Iranians said the centrifuges would not be sealed by the IAEA, but would instead be monitored by cameras.
ElBaradei, the IAEA director general, said he was satisfied with the agreement.
"We have now therefore completed our verification of Iran's decision to suspend enrichment and reprocessing-related activities," he said.
The IAEA board of directors then passed a resolution welcoming Iran's cooperation in the non-legally binding agreement.
The United States has long alleged Iran was building a nuclear arsenal, and repeatedly threatened to seek U.N. sanctions against Tehran.
