Usage tips
Separable verb
'Umziehen' is a separable verb. In a main clause, the prefix 'um' goes at the end. In subordinate clauses and infinitive constructions, the verb stays together.
EXAMPLE
Meine Schwester zieht nächsten Monat um.
My sister is moving next month.
Reflexive or not?
Pay attention to the reflexive pronoun: 'sich umziehen' means 'Kleidung wechseln' (to change clothes). Without 'sich', 'umziehen' usually means 'den Wohnort wechseln' (to change residence / move). This is a very important difference.
EXAMPLE
Ich ziehe mich schnell für das Abendessen um.
I'm quickly changing clothes for dinner.
Prepositions when moving
When you talk about changing residence, you often use prepositions. Use 'nach' for cities and countries and 'in' (+ accusative) for apartments, houses, or streets.
EXAMPLE
Er ist von Berlin nach Hamburg umgezogen.
He moved from Berlin to Hamburg.
Context clue
The meaning 'to move in a group' becomes clear from the context. It is often found in descriptions of festivals, parades, or demonstrations, usually with a location phrase like 'durch die Straßen' (through the streets).
EXAMPLE
Beim Schützenfest ziehen die Vereine durch das Dorf um.
At the marksmen's festival, the clubs parade through the village.

umziehen vs ziehen
to pull / move
'ziehen' and 'umziehen' can both mean that someone changes their place of residence. 'ziehen' is often used with a destination: you move into an apartment, to Berlin, or in with your parents. 'umziehen' more strongly describes the whole change from one apartment or house to another. That is why it is very natural to say: 'Wir ziehen nächste Woche um.' (We're moving next week.) Learners may confuse the words because 'ziehen' in this meaning is already part of 'umziehen'. Also important: 'sich umziehen' means to change clothes, not to change where you live.
umziehen
Nach der Trennung zieht mein Kollege in eine andere Stadt um.
After the breakup, my colleague is moving to another city.
ziehen
Sie zieht im Sommer in eine kleinere Wohnung.
She is moving into a smaller apartment in the summer.
