Police have not been able to locate 16-year-old Beth Wilkinson after she fell from the Humber Bridge.
Investigating officers had previously informed the Humber Coastguard that their "active searches" were on hold until further announcements.
A spokesman for the force said: "All reasonable searches for the girl have now been undertaken including extensive river bank and river searches involving numerous emergencies services, but she has not been located.
"She remains a registered missing person. The girl's family has been receiving support from specialist officers throughout the searches, to ensure they are aware of the activity undertaken as part of the missing person enquiries."
A coastguard spokesman said: "We are not conducting any searches today. The search has been called off until we receive new information."
Police were called to the bridge last Thursday morning after fears for the safety of the teenager who was the wrong side of the railings. She was then seen to fall from the bridge into the river.
The teenager is a former pupil of Wolfreton School in Kirk Ella, in East Riding, and from the west Hull area.
On Friday, friends laid flowers at Hessle Foreshore in an emotional vigil for the teenager.
