An Ethereum address identifies an account; a transaction hash identifies a transaction. Both commonly appear as 0x-prefixed hexadecimal strings, so the prefix alone does not tell you which kind of value you have.

## Start with the purpose of the field

Ask what the destination field expects before inspecting the string. A recipient field, an account search and a transaction lookup represent different tasks. Copying a value from a block explorer without keeping its label can remove the most useful clue about what it identifies.

In a team record, keep separate fields for the public address and any transaction reference. Do not use a generic “hash” column for both. Specific labels help reviewers catch a paste error without needing to infer the original workflow.


## Length is a check, not proof of correctness

An Ethereum address is a 20-byte value, commonly displayed as 40 hexadecimal characters after 0x. A transaction hash is normally a 32-byte value, shown with 64 hexadecimal characters after that prefix. This difference can expose an obvious mismatch, but a string with the right length still needs context.

Do not shorten a transaction hash to make it fit an address field. That creates a different value rather than correcting the error. Return to the source, identify the account address you intended to use and compare the complete value.


## Keep link labels and destinations consistent

A link labelled “View account” should lead to the intended account view, while a transaction reference should open the relevant transaction view. Inspect both the visible label and the destination. A correctly formatted hyperlink can still point at the wrong type of record.

Record the intended network alongside the link. A familiar account identifier does not by itself tell a reader which network state to inspect. The [cross-chain address guide](https://www.ethvanity.com/blog/same-address-every-evm-chain) explains why this distinction matters.


## Review copied values in a plain-text record

When preparing documentation, paste each value into its own labelled field. Compare it with the original source before moving it into a screenshot or presentation. This simple intermediate step reduces confusion caused by truncation or formatting.

Use the [hex and checksum guide](https://www.ethvanity.com/blog/ethereum-vanity-address-hex-checksum) for address representation. A checksum is an aid to checking an address representation, not a certificate that you copied the intended recipient or selected the intended network.
