If your ACI envelope was already sent to NAFEZA, there is no option to recall or undo the filing.
If you need to resend a corrected/updated document or add a missing document to your previous ACI filing, just compose a new Egypt ACI envelope, enter the same ACID number as before, and upload the new or corrected document(s).
Info
As long as the ACID number is the same, the ACI filing fee will not be charged again. You will still have to pay the document transfer fee (3 units (𝕌) per document, but never more than 15 units (𝕌) per ACID number).
For example, if you have already transferred 5 documents with the first envelope, any subsequent transfers under the same ACID number will be free of charge.
