Does S3 UploadPartCopy support copying object from one region to another?

Question

I'd like to copy a large object that over 5GB from one region to another region (different account).

Amazon S3 supports copy operations using access points only when the source and destination buckets are in the same AWS Region.

So looks like I can't use access point to copy between regions.

A regular s3 object url is bucket-name\file-name, how do I specify source region and the source account number in the UploadPartCopy API? Or, does S3 UploadPartCopy support copying object from one region to another?

Yes, s3 objects up to 5GB in size may be copied between buckets, even when those buckets are in different regions. You cannot use the accelerator but the API itself supports your need.

See the CLI documentation for the copy-object operation, which covers how to form the request (SDK operations in your programming will operate very similarly).
