How can I keep work and personal contacts separate without maintaining two copies of everyone?

Treat the account a contact is saved in as the main way to separate the two groups. For example, save a colleague you contact for work in your work account, and a friend in your personal account. If the same person is both a colleague and a friend, choose one account for the single record, based on where you most need to find and maintain it; don’t copy the entry just to make it appear in both places.

Then use account-based views when you want to focus on one group, if your contacts app offers them. On iPhone, Apple documents adding contact accounts such as iCloud, Exchange, Google, and Yahoo, viewing contacts from those accounts, and choosing a default account for new contacts. [S1] Those details apply to the iPhone guidance cited here; they don’t establish how every device or contacts app handles accounts or views.

Pick the account that best fits your everyday use of that contact, and apply the same rule consistently. Ask yourself: Is this mainly a work relationship? Do I usually look this person up in my work or personal contacts? Which account should hold the record I’ll update if their details change?

Here’s a simple illustrative rule: “Save people I primarily contact for work in [work account]; save personal contacts in [personal account]. For people in both groups, save one record in [chosen account] and use [account-based view or search method] to find it.” These bracketed labels are placeholders, not instructions about a particular employer’s setup. If your organization has a required account or contact-handling policy, check that before choosing.

Check the default account or save-location setting before you create the next entry. On iPhone, Apple says users can select a default account where new contacts are automatically added. [S1] The practical check is: open the contact-creation screen, look for the account or list shown as the destination, and confirm it matches your intended location before saving. The exact control and its label can differ by app, so use that app’s own settings or help if the destination is unclear.

For an existing entry in the wrong account, first confirm which account contains it and whether your contacts app provides a supported way to move it. Don’t create a second copy as a workaround unless you deliberately need a separate record. The cited Apple guidance establishes account viewing and a default for new contacts; it does not describe every app’s options for moving, merging, or syncing contacts.

Use this routine: identify whether the contact is mainly work or personal; choose the corresponding account; check the destination shown when creating the entry; save one record; then view that account to confirm where it appears. If you can’t tell which account received it, pause and inspect the account or list setting before making another entry.

For a quick check of the overall arrangement, open the work-only and personal-only views, if available, and confirm that each shows the expected contacts. On iPhone, Apple says turning off an account stops its contacts appearing on the iPhone, while those contacts remain in the internet account and on other devices already configured with that account. [S1] So disappearing from that iPhone view does not, by itself, mean the contact was deleted from the account. This source does not establish what happens on other platforms or in every contacts app.
