What is the exact value of the data you would like to convert to Int64?

"33300109396272646795 "

A "shipper id" is a nonsense number; probably made up of sub-fields. You're probably wanting an (sql) "entity / identity id" instead.

See Int64 Struct (System) | Microsoft Learn[^] for upper and lower limits. You could use a Decimal Struct (System) | Microsoft Learn[^] type, but it rather depends on what you are trying to do with this value.

The error message is indicating exactly what is wrong.

You are trying to convert a string "33300109396272646795" to an INT64 numeric value.

If you compare the value
33300109396272646795

to the maximum value for an INT64
9223372036854775807

you can see, that "33300109396272646795"
cannot be converted to INT64.
It is too big!

See Int64.MaxValue Field (System) | Microsoft Learn[^]

It might also be a good idea to read this documentation about C# numeric types:
Integral numeric types - C# reference | Microsoft Learn[^]

A solution would be to use a different conversion method "Convert.ToUInt64" as described here:
Convert.ToUInt64 Method (System) | Microsoft Learn[^]

UInt64 can hold values from 0 to 18,446,744,073,709,551,615
